Purpose Inguinal hernias are a long-term complication of radical prostatectomy (RP). We investigated the clinical features and surgical outcomes of patients with inguinal hernias developing after RP. Methods We retrospectively investigated 80 patients (86 hernias) who underwent inguinal hernia repair after RP. We repaired all RP-associated inguinal hernias by the tension-free method with a mesh plug. We also retrospectively investigated 729 adult male patients (779 hernias) who underwent inguinal hernia repair as a control group. Results A higher proportion of the 80 post-RP patients developed right-sided hernias (53 [66%]) than the controls, which was significant. A higher proportion of the 86 post-RP hernias were indirect (76 [89%]) than the controls, which was also significant. The mean times to hernia development after robot-assisted RP, laparoscopic RP, and radical retropubic prostatectomy were 20.3, 48.9, and 73.2 months, respectively. The total complication rates did not differ significantly between the post-RP group and control group. Conclusion The proportion of post-RP patients with right-sided hernia was significantly higher than controls. Indirect inguinal hernias were predominant among the post-RP hernias. The mesh plug method is safe and effective for inguinal hernia repair after RP. The time from robot-assisted RP to the development of inguinal hernia was shorter than those from laparoscopic RP, and radical retropubic prostatectomy.
